Through experimental reproduction of the decomposition process using the cadaver of rabbit Oryctolagus sp., the dynamics of cadaver microflora was studied; the dominant bacterial taxa were isolated in pure culture and identified; their ecological and trophic profiles and biodiversity were described based on the values of Simpson and Menchinic ecological indices. The dependence of cadaver rotting and skeletonization rate on the taxonomic profile of microorganisms, decomposition period, and abiotic environmental factors (temperature, acidity, soil moisture) was demonstrated. The data obtained contribute to justifying the use of microbiological methods in forensic practice. To establish objective causality patterns of microbial transformation of organic matter in nature, further targeted study of ecological patterns of cadaveric microflora is necessary.

Objectives: Chronic skin diseases (CSD) may lead to productivity losses. This mixed-methods study investigated symptom severity, social challenges, need for workplace accommodation, sick leave and their association with perceived impaired work performance (IWP) among workers with CSD.
Methods: Data were collected from April to June 2023.

The escalating demand for sustainable materials has been fueling the rapid proliferation of the biopolymer market. Biodegradable polymers within natural habitats predominantly undergo degradation mediated by microorganisms. These microorganisms secrete enzymes that cleave long-chain polymers into smaller fragments for metabolic assimilation.

Topography has an important influence on plant-soil relationships. However, research on plant-soil relationships in alpine grassland at the slope aspect and slope position scales is currently inadequate. In this paper, based on the topographic and geomorphological characteristics of the study area, alpine grassland with typical slope aspect and slope position conditions was selected as the research object.

Vegetation restoration potential (VRP) assessment is an important aspect and foundation of ecological restoration projects. Neglecting the carrying capacity of the natural environment in the formulation and implementation of ecological restoration projects often leads to diminished effectiveness or even environmental damage. Existing models for VRP either overly rely on empirical knowledge, resulting in low efficiency and reproducibility, or fail to consider the nonlinear relationship between the natural environment and vegetation cover, leading to low accuracy in assessment results.

Due to the unique geographical features of large numbers, isolated by water and diverse formation histories, islands have become natural laboratories for ecological and evolutionary research. Islands have a high proportion of endemic species and disharmony in representing the species compared with that in the continent, which provides a good opportunity to explore the formation of island biodiversity. In this review, we focuse on island ecosystems and describes the progress of research in island biogeography in recent years from three aspects: formation, maintenance, and loss of island biodiversity.
